Hi Chris,

I really appreciate your new post regarding the setup of ASA 5500 series, I have some confusion though, regarding the 5505 datasheet on the virtual Interface " 3 ( no trunking
suppport) / 20 ( with trunking support ) since Im going to use our ASA 5505 as router as well
my question is do I need to purchase License for Inter Vlan? or it is already on the
trunking Function? Thanks in Advance..

Dexter,

I'd advise you to read the following link/document which clearly states how the interfaces and licenses work, so you know which part number to order:

Hi Cris,

Its me again, thanks once again for the informative post you did
apparently I'm having problem on our 5505 FW I was wondering what configuration I missed out
on port forwading http port 80 to our local server.

CISCO ASA 5505 OS Version 8.4.2
Public IP. 210.4.109.XX
Local webserver: 10.0.1.155

right now we are using a netgear router and the port forwarding is working okay when I switch
it to the cisco FW, it only work on locally ( 10.0.1.155 ) accesing it outside doesn't work
heres my configuration below


object network Host-A

host 10.0.1.155


Object Network Outside_IP

host 210.4.109.xx


Object Service TCP_HTTP

service tcp source eq 80




!im using Outside interface IP

nat (inside,outside) source static Host-A interface service TCP_HTTP TCP_HTTP


access-list out_in permit tcp any host 10.0.1.155 eq 8


access-group out_in in interface outside

!
!

Please kindly help on my issue

thanks

Regards,
Dexter

I have read the basic config guide and is still having an issue with getting Internet access to the vlans on the routers behind the firewall.


Comcast connected to ASA 5505 vlan 2 port E0/0. Port E0/2 in vlan 1 connected to 2950 switch as an access port. There is a Cisco 2821 with several vlans also connected to the 2950 switch. Trying to get traffic from the vlans out to the internet.

I have tried creating another sub interface on the router for the ASA and putting E0/0 into that vlan but still no Internet access for the vlans.
